Process for recovery of nickel and Cobalt from laterite ores using Ionic exchange resin

摘要

The process according to the invention, comprises the following steps: (a) (1) of laterite Ore (OR) through crushing, Separation, scrubbing, Wear, and High Intensity Magnetic Separation; (b) (2) of leaching fraction obtained from non-magnetic (CN) The previous Stage (a); (c) optionally,(3) Neutralization of liquid waste of the leaching stages and / or solid-liquid separation (4); (d) treatment of the residual Liquid of the stages (b) or (c) use a Hybrid System of Ion Exchange (5) containing at least one Circuit for the clearance of the impure Zas and at least a Circuit for the Recovery of nickel and Cobalt extraction; (e) (6) of the reSina ion exchange is used; (f) separation, purification, (7) and Recovery of nickel and Cobalt.
